Hi,

I am running a gentoo xen dom0, with a few gentoo domU guests and a
windows 2008 server HVM, all are 64bits versions.

Now, I need a 32bits linux guest, so I (cross-) compiled a 32bits
kernel and prepared a 32bits minimal disk. I tried to make sure I kept
the same kernel parameters as for my 64bits guests. I am running xen
4.0.0, PAE is not enabled and tmem is not started.

When I try to boot my new 32bits domU, it will crash while loading the
kernel with a "BUG: unable to handle kernel paging request at ..."

Here is what is logged to the console:
